Britain's Prince William sends strong message from tank near Russian border, reports say BBC.

He came to Estonia to support British troops in what is now the British Army's largest operational deployment abroad.

During his two-day trip to Estonia, Prince William visited some of the 900 British soldiers in the multinational force, including soldiers from the Mercian Regiment of which the prince is Colonel-in-Chief.

The prince, who wore a NATO badge on his uniform, was shown field training for this battle group, where he also met with Estonian and French soldiers.
